Bored and horny, step-siblings Michelle and Harry find their shared space cramped and their patience thin. Michelle, a trans teen, can't help but tease her brother with her curves and her filthy talk, knowing he's too 'nice' to act. But when she starts riding a dildo on the couch, he can't hold back any longer. He grabs her, lifts her up, and impales her on his thick cock, fucking her hard and deep in every position they can manage in their tiny room. Their moans fill the air as they give in to their taboo desires, fucking till they both collapse, spent and satisfied.
